Official title
Prospective, Multi-cohort, Exploratory Clinical Study of Pyrrotinib Maleate in HER2-positive Early Breast Cancer
Overview
This is a Multi-cohort, Phase II Clinical Study of Neoadjuvant - Adjuvant Pyrotinib in the Treatment of HER2-positive Early Breast Cancer, To evaluate the efficacy and safety of the pyrotinib-containing study regimen in patients with early HER2-positive early breast cancer with neoadjuvant and postoperative different Residual tumor burden (RCB) scores.
Detailed description
This is a Multi-cohort, Phase II Clinical Study of Neoadjuvant - Adjuvant Pyrotinib in the Treatment of HER2-positive Early Breast Cancer, To evaluate the efficacy and safety of the pyrotinib-containing study regimen in patients with early HER2-positive early breast cancer with neoadjuvant and postoperative different Residual tumor burden scores.
Interventions
- Drug Pyrotinib
Patients who meet the screening criteria will receive pyrotinib (400mg, qd) + trastuzumab injection (first dose 8mg/kg, subsequent 6mg/kg, d1) + albumin purpurenin.In adjuvant therapy, pathological complete response patients receive pyrotinib time to one year, non-pathological complete response patients with RCB-1 receive Trastuzumab Emtansine time to one year，RCB≥2 were treated with Trastuzumab Emtansine combined with pertuzumab time to one year.
Primary outcome measures
- Event Free Survival(EFS) [Time frame: 3 year]
Secondary outcome measures (1)
- total pathological complete response(tpCR) [Time frame: 24 month]
Eligibility criteria
Inclusion criteria

- Pathological examination confirmed HER2 positive (immunohistochemistry staining +++ or immunohistochemistry staining ++ and Fluorescence in situ hybridization positive);
- Patients with invasive breast cancer diagnosed histologically plus imaging as early (T1c-3, N0-1, M0) or locally advanced (T2-3, N2, or N3, M0);
- Eastern Cooperative Oncology Group score 0\~1;
- Plan to undergo the final surgical removal of breast cancer, i.e. breast conserving surgery or total mastectomy, sentinel lymph node (SN) biopsy or axillary lymph node dissection (ALND);
